Synopsis"Wedding" is one of those rare stories that provide a glimpse into the "lived-happily-ever-after" life of a newlywed couple. The series begins with the wedding ceremony of the two main characters.

A daughter of a rich family and a music college graduate, Se-na (played by Jang Nara) works as a house manager at a theater, and is one day introduced to Seung-woo (played by Ryoo Shi-won), a diplomat. Soon, the two tie the knot only because they "fit" each other, but as time goes by, they clash over virtually every issue due to their widely different backgrounds and life values.

As the marital discord grows, Seung-woo gradually falls in love with Yun-soo (played by Myung Se-bin), his childhood sweetheart, who is so much different from his reckless wife Se-na. But watching Seung-woo grow aloof from her, Se-na, on the contrary, starts feeling attracted to him and decides to do her utmost to captivate his heart for good.
